Thanks to a special woven structure, these sliding bearings made of composite material warranty excellent friction properties and improved wear resistance without external lubrication even under high loads.
H-Liner™ M products are manufactured with an homogeneous woven sliding polymer, on the complete wall thickness. Mechanical characteristics are near from brass and don't require any greasing.
|Max. dynamic contact pressure||Max. static contact pressure||Max sliding speed||Max temperature||Thermal expansion coefficient||Water absoption (24h)|
|80 MPa||350 MPa||0.5 m/s||-40°C +130°C||4 E-5/°C||0.10 %|
For optimal performance we recommend to use grinded pin with a roughness lower than Ra 0,4 μm and hardness higher than 400 HB. HEF DURFERRIT PEL™ OX pin are particularly appropriated to work against H-Liner™ bushings.
- Maintenance free
- Enable machining of pieces with complex shape
- Low water absorption
- Low weight
- Misalignement resistance properties
H-Liner™ M bearings are best assembled by press fitting or by nitrogen mounting (Other assembly techniques can also be used, ex: glue). For further information, please contact HEF DURFERRIT prior to use.
